반응 단계
7-Nitro-5H-pyrrolo[2,3-b]pyrazine (5) is prepared by adding 5H-pyrrolo[2,3-b]pyrazine (3) to fuming nitric acid while cooling (e.g. 0° C.). After stirring for one to several hours, water is carefully added and the mixture neutralized with saturated sodium bicarbonate. The solids are collected by filtration and dried to provide 7-nitro-5H-pyrrolo[2,3-b]pyrazine 5.
